Pharmacodynamic Evaluation of Suppression of in Vitro Resistance In
www.nature.com/scientificreports OPEN Pharmacodynamic evaluation of suppression of in vitro resistance in Acinetobacter baumannii strains using polymyxin B‑based combination therapy Nayara Helisandra Fedrigo1, Danielle Rosani Shinohara1, Josmar Mazucheli2, Sheila Alexandra Belini Nishiyama1, Floristher Elaine Carrara‑Marroni3, Frederico Severino Martins4, Peijuan Zhu5, Mingming Yu6, Sherwin Kenneth B. Sy2 & Maria Cristina Bronharo Tognim1* The emergence of polymyxin resistance in Gram‑negative bacteria infections has motivated the use of combination therapy. This study determined the mutant selection window (MSW) of polymyxin B alone and in combination with meropenem and fosfomycin against A. baumannii strains belonging to clonal lineages I and III. To evaluate the inhibition of in vitro drug resistance, we investigate the MSW‑derived pharmacodynamic indices associated with resistance to polymyxin B administrated regimens as monotherapy and combination therapy, such as the percentage of each dosage interval that free plasma concentration was within the MSW (%TMSW) and the percentage of each dosage interval that free plasma concentration exceeded the mutant prevention concentration (%T>MPC). The MSW of polymyxin B varied between 1 and 16 µg/mL for polymyxin B‑susceptible strains. The triple combination of polymyxin B with meropenem and fosfomycin inhibited the polymyxin B‑resistant subpopulation in meropenem‑resistant isolates and polymyxin B plus meropenem as a double combination sufciently inhibited meropenem‑intermediate, and susceptible strains. T>MPC 90% was reached for polymyxin B in these combinations, while %TMSW was 0 against all strains. TMSW for meropenem and fosfomycin were also reduced. Efective antimicrobial combinations signifcantly reduced MSW. The MSW‑derived pharmacodynamic indices can be used for the selection of efective combination regimen to combat the polymyxin B‑resistant strain. -

Antimicrobial Surgical Prophylaxis
Antimicrobial Surgical Prophylaxis The antimicrobial surgical prophylaxis protocol establishes evidence-based standards for surgical prophylaxis at The Nebraska Medical Center. The protocol was adapted from the recently published consensus guidelines from the American Society of Health-System Pharmacists (ASHP), Society for Healthcare Epidemiology of America (SHEA), Infectious Disease Society of America (IDSA), and the Surgical Infection Society (SIS) and customized to Nebraska Medicine with the input of the Antimicrobial Stewardship Program in concert with the various surgical groups at the institution. The protocol established here-in will be implemented via standard order sets utilized within One Chart. Routine surgical prophylaxis and current and future surgical order sets are expected to conform to this guidance. Antimicrobial Surgical Prophylaxis Initiation Optimal timing: Within 60 minutes before surgical incision o Exceptions: Fluoroquinolones and vancomycin (within 120 minutes before surgical incision) Successful prophylaxis necessitates that the antimicrobial agent achieve serum and tissue concentrations above the MIC for probable organisms associated with the specific procedure type at the time of incision as well as for the duration of the procedure. Renal Dose Adjustment Guidance The following table can be utilized to determine if adjustments are needed to antimicrobial surgical prophylaxis for both pre-op and post-op dosing.

In Vitro Susceptibilities of Escherichia Coli and Klebsiella Spp. To
Jpn. J. Infect. Dis., 60, 227-229, 2007 Short Communication In Vitro Susceptibilities of Escherichia coli and Klebsiella Spp. to Ampicillin-Sulbactam and Amoxicillin-Clavulanic Acid Birgul Kacmaz* and Nedim Sultan1 Department of Central Microbiology and 1Department of Microbiology, Faculty of Medicine, Gazi University, Ankara, Turkey (Received January 30, 2007. Accepted April 13, 2007) SUMMARY: Ampicillin-sulbactam (A/S) and amoxicillin-clavulanic acid (AUG) are thought to be equally efficacious clinically against the Enterobacteriaceae family. In this study, the in vitro activities of the A/S and AUG were evaluated and compared against Escherichia coli and Klebsiella spp. Antimicrobial susceptibility tests were performed by standard agar dilution and disc diffusion techniques according to the Clinical and Laboratory Standards Institute (CLSI). During the study period, 973 strains were isolated. Of the 973 bacteria isolated, 823 were E. coli and 150 Klebsiella spp. More organisms were found to be susceptible to AUG than A/S, regardless of the susceptibility testing methodology. The agar dilution results of the isolates that were found to be sensitive or resistant were also compatible with the disc diffusion results. However, some differences were seen in the agar dilution results of some isolates that were found to be intermediately resistant with disc diffusion. In E. coli isolates, 17 of the 76 AUG intermediately resistant isolates (by disc diffusion), and 17 of the 63 A/S intermediately resistant isolates (by disc diffusion) showed different resistant patterns by agar dilution. When the CLSI breakpoint criteria are applied it should be considered that AUG and A/S sensitivity in E. coli and Klebsiella spp. -
B-Lactams: Chemical Structure, Mode of Action and Mechanisms of Resistance
b-Lactams: chemical structure, mode of action and mechanisms of resistance Ru´ben Fernandes, Paula Amador and Cristina Prudeˆncio This synopsis summarizes the key chemical and bacteriological characteristics of b-lactams, penicillins, cephalosporins, carbanpenems, monobactams and others. Particular notice is given to first-generation to fifth-generation cephalosporins. This review also summarizes the main resistance mechanism to antibiotics, focusing particular attention to those conferring resistance to broad-spectrum cephalosporins by means of production of emerging cephalosporinases (extended-spectrum b-lactamases and AmpC b-lactamases), target alteration (penicillin-binding proteins from methicillin-resistant Staphylococcus aureus) and membrane transporters that pump b-lactams out of the bacterial cell. Keywords: b-lactams, chemical structure, mechanisms of resistance, mode of action Historical perspective Alexander Fleming first noticed the antibacterial nature of penicillin in 1928. When working with Antimicrobials must be understood as any kind of agent another bacteriological problem, Fleming observed with inhibitory or killing properties to a microorganism. a contaminated culture of Staphylococcus aureus with Antibiotic is a more restrictive term, which implies the the mold Penicillium notatum. Fleming remarkably saw natural source of the antimicrobial agent. Similarly, under- the potential of this unfortunate event. He dis- lying the term chemotherapeutic is the artificial origin of continued the work that he was dealing with and was an antimicrobial agent by chemical synthesis [1]. Initially, able to describe the compound around the mold antibiotics were considered as small molecular weight and isolates it. He named it penicillin and published organic molecules or metabolites used in response of his findings along with some applications of penicillin some microorganisms against others that inhabit the same [4]. -
New Β-Lactamase Inhibitor Combinations: Options for Treatment; Challenges for Testing
MEDICAL/SCIENTIFIC AffAIRS BULLETIN New β-lactamase Inhibitor Combinations: Options for Treatment; Challenges for Testing Background The β-lactam class of antimicrobial agents has played a crucial role in the treatment of infectious diseases since the discovery of penicillin, but β–lactamases (enzymes produced by the bacteria that can hydrolyze the β-lactam core of the antibiotic) have provided an ever expanding threat to their successful use. Over a thousand β-lactamases have been described. They can be divided into classes based on their molecular structure (Classes A, B, C and D) or their function (e.g., penicillinase, oxacillinase, extended-spectrum activity, or carbapenemase activity).1 While the first approach to addressing the problem ofβ -lactamases was to develop β-lactamase stable β-lactam antibiotics, such as extended-spectrum cephalosporins, another strategy that has emerged is to combine existing β-lactam antibiotics with β-lactamase inhibitors. Key β-lactam/β-lactamase inhibitor combinations that have been used widely for over a decade include amoxicillin/clavulanic acid, ampicillin/sulbactam, and pipercillin/tazobactam. The continued use of β-lactams has been threatened by the emergence and spread of extended-spectrum β-lactamases (ESBLs) and more recently by carbapenemases. The global spread of carbapenemase-producing organisms (CPOs) including Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii, limits the use of all β-lactam agents, including extended-spectrum cephalosporins (e.g., cefotaxime, ceftriaxone, and ceftazidime) and the carbapenems (doripenem, ertapenem, imipenem, and meropenem). This has led to international concern and calls to action, including encouraging the development of new antimicrobial agents, enhancing infection prevention, and strengthening surveillance systems. -

As we know, the infections due to Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) began to plague in December 2019 in Wuhan City, Hubei Province, People's Republic of China. The disease was caused by SARS-CoV-2 infection which was later known as Coronavirus Disease 2019 (COVID-19) which in early 2020 began to spread to several countries and eventually spread to almost all countries in the world. On March 11, 2020, WHO announced COVID-19 as a global pandemic. In Indonesia, the first case was officially announced on March 2, 2020. Considering that the spread of COVID-19 has been widespread and has an impact on social, economic, defense, and public welfare aspects in Indonesia, the President of the Republic of Indonesia established the Task Force for the Acceleration of COVID- 19 Handling aiming to increase readiness and ability to prevent, detect and respond to COVID-19.
